When I run a program using the DrawText function the program crashes, example code: gd3dDevice->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 40, 100), 1.0f, 0); gd3dDevice->Clear(0, NULL, D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); gd3dDevice->BeginScene(); gd3dDevice->SetFVF(CUSTOMFVF); D3DXMATRIX matView; D3DXMATRIX matTranslate; D3DXMATRIX matScale; D3DXMATRIX matRotateZ; D3DXMatrixLookAtLH(&matView, &D3DXVECTOR3 (x, y, z), &D3DXVECTOR3 (x + 20.0f, y, 0.0f), &D3DXVECTOR3 (0.0f, 0.0f, -1.0f)); gd3dDevice->SetTransform(D3DTS_VIEW, &matView); D3DXMATRIX matProjection; D3DXMatrixPerspectiveFovLH(&matProjection, D3DXToRadian(45), SCREEN_WIDTH / SCREEN_HEIGHT, 1.0f, 8192.0f); gd3dDevice->SetTransform(D3DTS_PROJECTION, &matProjection); RECT R = {5, 5, 0, 0}; mFont->DrawText(NULL, _T("Text"), -1, &R, DT_NOCLIP, D3DCOLOR_XRGB(0,0,0)); gd3dDevice->EndScene(); gd3dDevice->Present(NULL, NULL, NULL, NULL); The font: ID3DXFont* mFont; D3DXFONT_DESC fontDesc; fontDesc.Height = 18; fontDesc.Width = 0; fontDesc.Weight = 0; fontDesc.MipLevels = 1; fontDesc.Italic = false; fontDesc.CharSet = DEFAULT_CHARSET; fontDesc.OutputPrecision = OUT_DEFAULT_PRECIS; fontDesc.Quality = DEFAULT_QUALITY; fontDesc.PitchAndFamily = DEFAULT_PITCH | FF_DONTCARE; _tcscpy(fontDesc.FaceName, _T("Times New Roman")); D3DXCreateFontIndirect(gd3dDevice, &fontDesc, &mFont); If I take out DrawText the program runs fine. Have I missed something? [Edited by - HarrisonPloeg on February 20, 2007 1:38:51 AM]

You don't seem to be checking any of the return values. Always do error checking, in Direct3D you can do this by checking the HRESULT returned by functions (or using the FAILED() macro).

Once you do this, it should give you more of an idea of what's causing the problem.

You might want to change you rectangle definition since it is incorrect.
It needs to be :

RECT R = {0, 0, 5, 5};

I don't know if thats what causing the crashes but it will prevent another forthcoming bug.

Also , r u sure the _T macro adds the terminating character to the string ? try replacing -1 with 4.
There is nothing that can't be solved. Just people that can't solve it. :)

Why does it fail every time I run the program?
I can't use the FAILED() macro because the program has stopped by the time I can check if it's failed.
The book "Introduction to 3D Game Programming with DirectX 9.0c: A Shader Approach", uses similar code to what I'm using, that example program works.

Did you try what I suggested above ? (changing -1 with 4 and redefining your rectangle)

In what way does it crash? Do you get an access violation? Does it just quit? Does your computer BSOD or reboot?

It's most likely to be an access violation reading 0x00000000, which means a null pointer. And since it crashes before the FAILED macro kicks in, it's a pointer bug, not a D3D bug. So, your mFont pointer is null or unset. Where do you set it? Do you check the return value from D3DXCreateFont()?

Excuse me for asking but you did initialized mFont before using it ?

Cause if the code is ordered is as you posted than the problem is quite obvious.

The exception information says the error code is 0xc0000005 the flag is 0x00000000.
It just asks me if I want to send an error report.

It says that End and Begin are not members of ID3DXFont.
mFont is initialized before it is used.

I you don't mind revealing your code I'll be happy to debug it on my computer cause its hard to figure it out like this.

You're not checking the return values of ANY of your Direct3D functions. If something goes wrong, D3D tells you by returning an error code. You're just effectively giving D3D the finger and assuming everything works fine. Which it doesn't, because D3DXCreateFontIndirect() is failing - As you'd see if you'd used the FAILED macro as people have suggested.
Because D3DXCreateFontIndirect() failes, your font pointer is NULL, which causes an access violation (0xc0000005) reading from the null pointer (location 0x00000000).

You should also use the debug runtimes, and link to d3dx9d.lib which will give you more error information in the debug output, such as telling you WHY the function failed.

Also, please use [ source ] [ /source ] tags when posting large chunks of text. It formats it nicely, and means people don't have to scroll down pages and pages to see the thread.
